Singapore Math

Has anyone used this approach? With the Common Core changes I wanted to know if this will work with the new standards and be helpful to the students. I don't know much about it and don't want to waste my time if you guys haven't had success with Singapore Math. Thanks for any feed back.

This is my 4th year using Singapore, and my 1st year using it in 4th grade. Singapore is above and beyond anything I have ever used in my 24 years of teaching. It is very challenging, only because the prior knowledge isn't there if they didn't use Singapore the previous year. Once you spend a few days blending the 3A and 3B books with the 4A and 4B books, is amazing what my children can do. Mental math skills, understanding of place value, find the partial volume of a rectangular prism, three step word problems to multiply fractions and decimals. I don't have the G and T class, just an amazing, hard working class. My principal is thankful Common Core is coming in.... what would they have done next year...

Here's the best part, the teacher's manual is about one inch thick, for the first and the second semester. The plans are clear, well written. You will love it!

Common Core did derive its standards from Singapore.
We just adopted Math in Focus, the Americanized version of Singapore Math. Read more about it on thinkcentral.com. The original program can be found on singaporemath.com. It is a rigorous program that includes international standards in addition to common core. Math savvy teachers will do fine from what I hear, and teachers who lack math confidence will learn TONS with quality training, support, and teacher collaboartion. Based on school visitations, ongoing teacher training is a must!
We are implementing a K-8 program next year, but as a fifth grade teacher I will need to use some 4th and even 3rd grade materials because it is so challenging.
